Mate, for £150 ill sort you out, i just need to check the bottle over and make sure its fit for the purpose as the fill nipple seems damaged, but works perfectly, what i have is follows:
ion - with a Freak barrel system, CP rail and Hybrid on/off button ASA
Viewloader Eyeforce Hopper
1.1l 3000PSI Steelie
All in good condition
with a 3k fill, you'd put out around 1500 balls at max velocity i'd say maybe?
Will shoot the best part of 15+bps and is a really nice starter marker and setup which you will enjoy!
PM if you're interested and ill sort you pics out
